Rpm, the suction chamber due to tooth meshing with each other gradually disengaged, seal work volume increases, the formation of a partial vacuum, and therefore the oil tank under the action of external atmospheric pressure, through the suction tube into the suction chamber Yangling hydraulic repair quote the tank is filled teeth Yangling hydraulic repair, and with the gear rotates, the oil pressure to the oil chamber. Yangling side hydraulic repair factory in pressure oil region, where due to the teeth gradually into the engagement, to seal the working chamber volume continues to decrease, the oil will be squeezed out, transporting oil from the pressure chamber to the pressure line to go. Between the gear end and end caps; between gears turning and the housing bore and the meshing of the two gears. Where the greatest impact on the leakage is an axial gap between the gear end and the end cap, through leakage axial clearance of the total amount of leakage can be 75 to 80 percent, because here a short leak paths, a large area of ??the leak. Axial gap is too large, the leakage volume, will reduce the volumetric efficiency; but the gap is too small, increase the mechanical friction losses between the gear end and the end cap, will reduce the mechanical efficiency of the pump. Therefore, the design must be strictly controlled and the axial clearance of the pump manufacturing. ② trapped oil gear pump to be smooth, overlapping coefficient gear must be greater than 1, Yangling hydraulic repair shop | Yangling hydraulic repair | Xi'an Xi'an Chengtong Chengtong hydraulic repair hydraulic repair Limited.
